The publicity stunt follows a successful Caustic Window Kickstarter campaign that saw £67,000 raised to release a rare 1990s test pressing. The latest missive from the campaign - I'm one of the backers - just mentioned some housekeeping details about a DigiPack release and mentioned nothing of a Pink Floyd-style PR coup.

I rang Oval Space, who are hosting Aphex's label mate Rustie next month for the debut of Rustie's new album Attak. I asked them if the blimp was anything to do with them. They issued a quick denial and told me it was a marketing exercise by Warp Records.
